How can I remove values array based on array other [duplicate]

Answer 1

You can do it by converting them to Sets.

var arrayOne = [1,2,3,4,5,6,7,8]
var arrayTwo = [1,2,4,5,6,7]

let set1:Set = Set(arrayOne)
let set2:Set = Set(arrayTwo)

Use ExclusiveOr to do this.

    //Swift 2.0
    set1.exclusiveOr(array2) // result = {3,8}

   //Swift 3.0
   set1.symmetricDifference(set2) // result = {3,8}
